Anton Flettner, well known for his helicopters in Germany emigrated to the USA in 1947 and
founded the Flettner Aircraft Corporation. There he designed a heavy lift helicopter with
gas powered intermeshing rotors. Forward propulsion was given by two propellers, the rotors
should turn freely during forward flight and only be powered for take-off and landing, or low
speed flight. Rotor diameter was 23.5 m, length25.8m and payload about 3 tons. The compound
helicopter was desiganted Model 201.
